Abstract : Sewage and industrial wastewater pollution is a major environmental problem, especially from industries such as dyeing industries, which produce large amounts of heavy metals such as chromium (VI), which consider a major threat to human health and other organisms. In recent years, interest has increased with the use of many solid phase extractor after loading with nanosized metal oxides. Thus, this study included the following: i. The reuse of polyurethane as a solid waste that is a burden on the environment and its use after treatment and loading of ion pairing reagent tetrazolim chloride (TZ+Cl-) in the presence of iron (III) oxide (Fe2O3) nanosized. ii. Polyurethanes were used after treatment and loaded with iron (III) oxide (Fe2O3) nanosized as a solid sorbent and inexpensive type for removal of chromium (VI) ions from the aquatic media by formation of halochromate [CrO3Cl-] in the presence of hydrochloric acid. iii. The effect of different parameters on chromium (VI) retention have been studied, then it was possible to study the kinetic and thermodynamic behavior of the chromium (VI) ion extraction. by the used solid phase extraction were performed by batch mode of separation. iv. Determinition of most probable retention mechanism and using of modified polyurethane after packed in a chromatographic column to separate and remove of the Cr(VI) and Cr(III) ions after oxidation by hydrogen peroxide over the medium of potassium hydroxide with excellent efficiency. v. The column packed with the modified PUFs can also be used to separate chromium ions from environmental samples from water.
